Mark information issuing method and system

ABSTRACT

A mark issuing server operated by a mark issuer manages mark information collectively. A terminal of a user sends an information providing request to an information providing server of an information provider, and issues a mark issuing request to the mark issuing server on the basis of the information providing request. The information providing server searches for information corresponding to the information providing request from the terminal of the user, and provides the terminal of the user with information including requested information and location information of the mark issuing server. The mark issuing server determines validity of information provided from the information providing server on the basis of the mark issuing request, and sends a mark to the terminal of the user when the validity is verified, and the terminal of the user displays the mark with the information provided from the information providing server.

TECHNICAL FIELD

[0001] The present invention relates to a mark information issuing method and the system. More particularly, the present invention relates to a mark information issuing method and the system for displaying a mark issued by a mark issuer on a part of information when a user obtains the information from an information provider and displays the information, in a network in which an indefinite number of users, the information provider and the mark issuer issuing the mark to be displayed on the part of the information exist.

BACKGROUND ART

[0002] When displaying a mark on a part of information provided by the information provider, the following technique is used. The mark issuer issues the mark information beforehand to the information provider. The information provider stores the mark information in an information providing server. According to a providing information display request by a user, the mark information together with providing information are obtained and displayed.

[0003] Also, there is a following technique. The mark issuer notifies the information provider of information on the location of the mark beforehand. The information provider embeds location information of the mark information in the providing information, and obtains the providing information and the mark information from the mark location, and displays the providing information and the mark information according to a display request of the user.

[0004] However, according to the above-mentioned conventional technologies, when displaying a mark on a part of information provided by the information provider, management of the issued marks depends on the information provider. Accordingly, for example, if the term of validity is set for issuing the mark, there is a problem in that the mark can be used invalidity since the information provider can issue the mark information even after the term of validity is expired.

[0005] In addition, since the mark provider notifies the information provider of the information on the location of the mark information beforehand, information for obtaining the mark information is embedded in the information provided by the information provider. Therefore, there is a problem in that an information provider that intends to use the mark information invalidity can produce providing information by using the location information and can provide the providing information from the information providing server as if to provide providing information validly.

[0083] Next, the operation of the above-mentioned configuration will be described.

[0084]FIG. 4 is a sequence chart of the mark information issuing system of the present invention.

[0085] Step 101) The user 10 performs an information providing request operation 501 on the terminal 20 for requesting providing information stored in the information providing server 30. The terminal 20 detects the information providing request operation from the user 10, and performs an information providing operation process 601 for producing an information providing request signal 502 including an information providing request identifier by using the user operation detection part 201 and the information providing request sending part 202.

[0086] Step 102) The terminal 20 sends an information providing request signal 502 to the information providing server 30. The information providing server 30 receives the information providing request signal 502 from the terminal 20, and the information providing server 30 performs providing information sending process 602 for producing providing information that includes display information and mark issuing request information by using the providing information receiving part 301, the providing information search part 302, the providing information storing part 303 and the providing information sending part 304.

[0087] Step 103) The information providing server 30 sends a providing information sending signal 503 to the terminal 20. The terminal 20 receives the providing information sending signal 503 from the information providing server 30, and performs receiving information process 603 by using the provided information receiving part 203, the receiving information process part 204 and the receiving information display part 205.

[0088] Step 104) The terminal 20 displays content of the display information as the providing information display result 504 for the user 10.

[0089] Step 105) The terminal 20 sends a mark issuing program request signal 505 that includes a mark issuing program request to the mark issuing server 40. The mark issuing server 40 receives the mark issuing program request signal 505 from the terminal 20, and performs a mark issuing program sending process 604 by using the mark issuing request receiving part 401, the mark issuing request process part 402, the mark issuing program search part 403, the mark issuing program storing part 404 and the mark information sending part 409.

[0090] Step 106) The mark issuing server 40 sends a mark issuing program sending signal 506 that includes the mark issuing program to the terminal 20.

The issuing result information is “issue complete” or “search impossible”.

[0108] In the following, the operation of this embodiment will be described with reference to FIG. 4.

[0109] When the user performs the information providing request operation 501 on the terminal 20 (step 101), the terminal 20 issues the information providing request signal 502 (information providing request identifier (FIG. 5)) to the information providing server 30 (step 102).

[0110] Then, the information providing server 30 searches the providing information storing part 303 shown in FIG. 6 by using the providing information location identifier, and provides the terminal 20 with the providing information sending signal 503 (providing information (FIG. 7)) (step 103).

[0111] Then, the terminal 20 displays the providing information display result 504 to display the providing information for the user 10 (step 104).

[0112] Next, when installing a program in the terminal 20, the terminal 20 issues the mark issuing program request signal 505 (mark issuing request identifier (FIG. 8)) to the mark issuing server 40 (step 105). The mark issuing server 40 searches the mark issuing program storing part 404 according to the mark issuing request identifier. Then, the mark issuing server 40 sends the mark issuing program sending signal 506 (mark issuing program search result identifier (FIG. 10)) to the terminal 20 (step 106). If abnormal end occurs, an error is set in “search result information” in the mark issuing program search result identifier. Accordingly, the terminal 20 displays the mark issuing program search error display result 507 to the user 10 for showing error information (step 107).

[0113] When the terminal 20 requests issuing of mark from the mark issuing server 40, the terminal 20 sends the mark issuing request signal 508 to the mark issuing server 40 (step 108). The mark issuing server 40 searches the determination condition storing part 406 on the basis of the mark issuing request signal 508. If the determination condition is satisfied, “issue possible” is set in the determination result of the mark issuing determination result identifier (FIG. 12). When “issue possible” is set in the mark issuing determination result identifier, the mark information search part 407 searches the mark information storing part 408 so as to set one of “search impossible”, “issue complete” and “issue impossible” in the mark issuing result identifier (FIG. 14). If the search is successfully done, the mark issuing server 40 sends the mark information sending signal 509 to the terminal 20 (step 109).

[0114] Accordingly, the terminal 20 displays the mark information display result to the user 10 (step 110).

[0115] Although, in the above-mentioned operations, an example is explained in which the mark issuing server issues the mark, the mark program can be provided to the terminal 10 of the user in the same way.

[0116] In addition, in the above-mentioned embodiment, the mark issuing program can be any program as long as it can be executed on the client side.

[0117] In addition, the mark can be issued to the user 10 by executing a program on the mark issuing server 40 without executing the mark issuing program on the terminal 20 of the user 10.

[0118] In addition, a plurality of information providing servers 30 and a plurality of mark issuing servers 40 may exist.

[0119] As mentioned above, according to the present invention, mark information is collectively managed in the mark issuing server operated by the mark provider. When the user requests providing information from the information providing server, mark display request is automatically made from the user. Then, mark information is provided one by one from the mark issuing server after checking validity of information provided by the information providing server. Accordingly, invalid use of mark such as use of mark whose validity has expired and illegal copy of mark can be prevented, so that mark issuing can be performed properly.

[0120] The present invention is not limited to the specifically disclosed embodiments, and variations and modifications may be made without departing from the scope of the invention.
